The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Fig. 1 shows the structural representation according to many pile holding devices of one aspect of the invention.With reference to Fig. 1, many pile holding devices comprise rotating shaft 10, big arm 11, cursor 12 and forearm 13.Wherein, rotating shaft is positioned at center, blower fan seat in the plane.Big arm 11 is sheathed in the rotating shaft 10, and can rotate around rotating shaft 10.The adjustable range of the length of big arm 11 is a 20-30 rice, for example 15 meters.One end of cursor 12 also is sheathed in the rotating shaft 10, can rotate around rotating shaft 10 equally.The other end of cursor 12 is connected with forearm 13, and the adjustable range of the length of cursor 12 is a 10-15 rice, for example 12 meters.Forearm 13 specifically comprises a connecting rod and two handgrips, and the centre of connecting rod is connected on the cursor 12, and two handgrips then vertically are connected in the connecting rod two ends respectively, and forearm 13 has the forearm center, and the forearm center is the line of centres of two handgrips.In addition, many pile holding utensils have several centers, position 141, be centered close on the same circle 14 with forearm, and several centers, position 141 are distributed on the circle 14.
Shallow sea wind power field many pile leaders frame foundation construction method is specific as follows described:
In center, blower fan seat in the plane, and with cargo ship location, cargo ship is used for transporting blower fan with the coordinate setting of many pile holding devices.At first, utilize boat-carrying GPS by self formula lifting platform, many pile holding device centre coordinates are moved to (about 2 meters of deviations) near the center, seat in the plane, then, utilize 3 anchor ships that 4 positioning anchors are drawn and be thrown into the seabed, the self lift type lifting platform accurately is positioned at pile holding device centre coordinate on the design seat in the plane (errors of centration is less than 200mm) by positioning anchor, next, the self lift type lifting platform begins the ballast cargo ship, lifting cargo ship (cargo ship being lifted away from the water surface) after ballast finishes by 4 supporting legs, after the hull bottom of cargo ship breaks away from the water surface with an amount of venting of ballast tank water, continuing lifting rises to the cargo ship hull from stopping about 6 meters on the lowest water level water surface, by the anchor ship cargo ship is dragged to self lift type lifting platform side, and throws 4 positioning anchor location.Above self lift type lifting platform location, steady ship and cargo ship about 2 days of time spent of location.
Then, steel pipe pile is fixed on many pile holding devices and carries out pile sinking.The cursor 12 that rotates many pile holding devices makes the forearm center corresponding to 141 places, center, a stake position to the forearm center.Two cover rigging upper ends are hung on respectively on two gib heads of crane, and every cover lockset all comprises 1 200T hanging beam, 4 100T shackles, 2 100T-32 rice wire rope and 2 100T-16 rice wire rope, and crane is the 800T crane.Then every cover rigging lower end is hung on respectively on the last hanger and following hanger of steel pipe pile.Then, the suspension hook of the crane that hoists is raised up to safe altitude with steel pipe pile, and erect until steel pipe pile slowly hoist simultaneously steel pipe pile upper end and decline steel pipe pile lower end.With the speed of 2-4 rice/min hoist steel pipe pile upper end and decline steel pipe pile lower end.Then, the rigging on the hanger of dismounting steel pipe pile lower end.The jib of revolving crane is positioned over steel pipe pile on the center, a stake position 141 of many pile holding devices, holds forearm tightly to catch steel pipe pile.The upper end of decline steel pipe pile, the steel pipe pile of drowning oneself is then removed the rigging on the hanger of steel pipe pile upper end.Utilize crane that pile hammer is worked the upper end that winches to steel pipe pile, and hammer, start pile hammer steel pipe pile is carried out continuous pile sinking.Repeat above step and carry out pile sinking remaining described steel pipe pile.
At last, jacket is placed on the steel pipe pile is in the milk.To the top, seat in the plane, the double hook of the crane that descends then is placed in the sleeve of jacket on each steel pipe pile the double hook that utilizes crane with the jacket lifting.By jack leveling jacket, make jacket upper flange gradient≤2 ‰.The grouting material is injected in the sleeve and the cavity between the steel pipe pile of jacket, wait for that grouting material intensity reaches 75%.
Advantage of the present invention is: a kind of adjustable many pile holding devices are installed on the self-rising crane platform; this many pile leaders of cover shallow sea area wind energy turbine set frame foundation construction method; have construction equipment at present now and increase a kind of adjustable many pile holding devices in conjunction with domestic; optimized traditional many pile leaders frame foundation construction method greatly; greatly reduce construction cost; improved efficiency of construction; advance the process of shallow sea area wind energy turbine set large-scale production greatly, greatly reduced coastal waters many pile leaders of wind energy turbine set frame foundation construction cost.Be specially: 1, solved the difficult problem that many piles are beaten at the accommodation; 2, fine center, the piling bar position relative position deviation of having controlled, having solved jacket needs a difficult problem customized; 3, improved the efficient of offshore construction greatly.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
